This is the achievement you get for visiting any geohash on your birthday. Celebrating your birthday at the geohash would be an excellent touch, and, depending on how you choose to celebrate, could score you another achievement such as the Picnic Geohash or Sex Geohash.

For another birthday-related achievement, which can be achieved on a day that is not your actual birthday, see the Origin geohash achievement.

In addition to the usual geohashing proof, please provide proof that it is your birthday, such as a driver's licence, birth certificate, voter registration card or notarized statement from your mother or delivery room physician.

If you plan on geohashing on your birthday, here is a suggestion. Issue party invitations with a link to the wiki and the geohash calculator, and explain that guests will only be able to find the location of the party on the morning of the actual event. You would thus score the Drag-Along Geohash achievement as well as the Birthday Geohash.
